That evidence informs her routine, but it does not make her temperature, duration, or frequency a universal prescription.”

“Manipulating the core body temperature through hot baths, showers, or saunas – which can have a paradoxical effect on reducing core body temperature – can have dramatic effects on our ability to fall asleep.”
